MAGIS-100 is a next-generation quantum sensor under construction at Fermilab that aims to explore fundamental physics with atom interferometry over 100-meter baseline. This novel detector will search for ultralight dark matter, test mechanics in new regimes, and serve as technology pathfinder future gravitational wave detectors previously unexplored frequency band. It combines techniques demonstrated state-of-the-art 10-meter-scale interferometers the latest technological advances of world's...
We report results of a new technique to measure the electric dipole moment $^{129}\mathrm{Xe}$ with $^{3}\mathrm{He}$ comagnetometry. Both species are polarized using spin-exchange optical pumping, transferred measurement cell, and transported into magnetically shielded room, where SQUID magnetometers detect free precession in applied magnetic fields. The result from one week campaign 2017 2.5 2018, combined detailed study systematic effects, is...
We report development of a highly accurate (parts per billion) absolute magnetometer based on $^{3}\mathrm{He}$ NMR. Optical pumping polarizes the spins, long coherence times provide high sensitivity, and electron shell effectively isolates nuclear spin providing accuracy limited only by corrections including materials, sample shape, magnetization. Our was used to confirm calibration, 32 ppb, magnetic-field sensors in recent measurements muon magnetic moment anomaly...
Polarized nuclei are a powerful tool in nuclear-spin studies and the search for physics beyond standard model. Systems which compare two nuclear species have thus far been limited by anomalous yet reproducible frequency variations of unknown origin. We studied self-interactions $^{3}\mathrm{He}\ensuremath{-}^{129}\mathrm{Xe}$ system independently addressing, controlling, measuring influence each component polarization. Our results directly rule out prior explanations shifts demonstrate...
We introduce a novel technique for enhancing the robustness of light-pulse atom interferometers against pulse infidelities that typically limit their sensitivities. The uses quantum optimal control to favorably harness multipath interference stray trajectories produced by imperfect atom-optics operations. apply this method resonant interferometer and achieve thousandfold phase amplification, representing 50-fold improvement over performance observed without optimized control. Moreover, we...

MAGIS-100 is a long-baseline atom interferometer that operates as quantum sensor. It will search for dark matter, probe fundamental science, and serve prototype gravitational wave detector in the 0.3 to 3 Hz frequency range. The experiment uses light-pulse interferometry where pulses of light create optics equivalents beamsplitters mirrors. Laser beam aberrations are key source systematic error MAGIS-100, accurately characterizing laser spatial profile therefore essential. In this paper, we...
